Calculate the test mode timeline position. This will use the ground truth test data if there is any, and uses the test anim sequence play offset in case no test ground truth has been set yet. So if you have a geometry cache or so specified as test ground truth, it would extract the current time value from that.
The time offset, in seconds, of our test data.
